Our resent invention relates generally to water lifting devices and moreparticularly to water lifting devices of the t pe described and claimedin Patent Num er 1,100,491 granted to Lucius G. Rose under date of June16, 1914, our primary object beingthe improvement and refinement of suchapparatus'so as to adapt the same to a wider range of^usefulnessincluding substantially deeper operations.

According t9 our invention, we pl'pose to eliminate the shaft supportingframe of the above patent and support the shaft by an up- Iright tube inconnection with which the vshaft is so mounted as to permit ofadjustment of the impeller in its casing from the upper end of the shaftas well as to create several bearings whose presence avoids whippin ofthe shaft, and provide for thefconstant ubrica- .20 tion of thesebearings.

In the accompanying drawing, which illustrates our present iiiventionand forms a l ,I part of this specification,

Referring now to this drawing, our improved water liftin devicecomprises a rotary bladed impe er mounted rigidly upon the lower end ofa shaft 11 within a two partcasin 12\whose upper and lower arts arewboltogetherand have centrally ocated upper and lower inlet openings 13, thevformer being around the'lower portion of the shaft 11. ,The casing 12also has a side outlet 14 and to this outlet a suitable dischar e pipe15 of flexible or rigid nature is coup ed use. The impeller casing 12is, inuse, submerged-within the water to be` lifted and is preferablymounted u on skids 16 soas to elevate substantially a ove the boso'm ofthe body of water in which it is h l l Above the casing 12, and securedat the outer ends of'its radial arms 17 upon bosses 18 of said casing,is a spider frame 19 having a centrally upstanding tubular portion 20.the oil being held against and a lower counter-bored boss 21 alinedwith tube 20. The shaft 10 upstandsv i through the boss 21 and tube 20and also through a tubular casing 22, the lower end of the latter ofwhich isconnected by a threaded coupling 23. In the counter-bore ofbelowthe upper end of shaft 11, is closed by a tubular ad]usting nut 26threaded therein and which surrounds the shaft and has an upper flan dhead 27 formin a support for a thrust arin 28 preferab y of antifrictiontype. To 51e upper portion of the casing '22 the lower en of a U-shapedbracket 29 is securel clamped and the upper. end of this brac et carriesan anti-friotion bearing' 30 for the upper end of the shaft 11 at a ointsubstantially above the upper end of t casing 22. 5

Above the bearing 28, a anged collar 31 is secured to the shaft 11 theflange of this collar resting on the said bearing so as to thus supportthe weight and downward thrust of the shaft 11 and impellerfO and permitof adjustment of the latter so as to clear and center the samevertically in the' 'nsl casing 11 by adjusting the nut26 at the upperend of the casing 22. A belt-driven wheel 32 is ke ed or otherwisefixedto shaft 11 above the anged collar 31 and upon that portion of the,shaft which isbraced an strengthened by the bracket 29. 'r

The length of the casing 22 is of course dependent upon the length ofthe shaft desired for anyparticular use, but where these parts areemployed of a length'likely to permit whipping of the shaft in thecasing, we propose internal 'bearings' of any suitable character suchfor instance as shown in Fi ures 5 and 6. In Figure 5 a bearing33 1sshown around the shaft within the casing, having an annular rib portionengaged between the ends of adjacentl casing sections connected byFigure 6 the tubular bearing 35 interfits the casing 22 around the shaftandv is held in place b a set screw 36 through the casing. t is o vious,however, that other internal will be lubricated thoroughl y since, inuse; the casing 22 forms therein an oil reservoir,

of the lower packing 24 which also acts to a. threaded coupling 34. In

We claim 1. A water lifting device includinga low-4.

er casing having in ets and an outlet,l a' rotary impeller therein, anupright shaft upon' the lower end of which said lmpeller is secured, atubular casing housing saidA shaft above the casing, means on the upperportion of the shaft whereby it may be driven, a nut threaded in andclosing the upper end. of said casing, a anged collar secured on theshaft above said nut, and an anti-friction bearing between said nut andsaid collar.

2. In a pump, a pump vcasing having an inlet andan outlet, a cylindricalcasing eX- tending vertically therefrom, a bracket supported from theupper end of the cylindrical casing-11nd provided with a bearing invertical a ement with the latter, a head received. in the upper end ofthe cylindrical casing, a shaft passing through the cylindrical casingwith one end disposed in the pump casing and its opposite end journalledin the bearing, a vertically -adjustable collar on the and head; and animpeller xedto the shaft and revoluble inthe pump casing, the headand`co1lar being adjustable to raise or lower the impeller whereby tocentralizethe lat- !.ter in the pump casing. a

3. In a pump, a pump casi-ng having inlet and outlet ports, aycylindrical casing extendlegs horizontal with one of them attached ablein the upper end of the cylindrical casing vertically from the pumpcasing, a U- shaped bracket arranged with its parallel 'f ing and havinga longitudinal bore, a rotary shaft passing longitudinally through thecylindrical casing and head with its upper end received in the' bearingand its lower end projecting into the pump casing, an impeller xedtovthe lower end of the shaft, and' an adjustable collar fixed to theshaft and` resty ing upon the head wherebyI to support the weight of theshaft and impeller, the head and collar being adjustable vertically topo- I sition the impeller with relation to the upper and lower walls ofthe pump casing.
